oa Picking First Break in Seismic Traces by Fractal Method

The determination of the first arrival time of seismic wave is important factor in seismic tomography. The Hausdorff fractal dimension of seismic traces based upon fractal theory is different before and after first break. The sudden change point of fractal dimension for seismic traces indicates the position of the first arrival time. In the present paper, the method for calculating Hausdorff fractal dimension of seismic traces and its application to the detection of arrival time of the first break are proposed.
